    Default how to pass a variable from a method to another

    in this code, i would like to know how to pass the convertedWorkArray from the first method to the second one ??
    N.B:
    1-both methods belong to the same class
    2-i dont want the method ( getsum) to receive any parameters from the (main), i just want to know how to set the (convertedworkarray) visible to the method (getsum)

    public  int []convertStrToInt() 
        	{
        		int [] convertedWorkArray = new int [workarray.length];
     
        		for (int i=0;i<workarray.length;i++)
        			convertedWorkArray[i]=Integer.parseInt(workarray[i]);
        		    System.out.println("Your array was converted into integers");
                return convertedWorkArray;
            } 
     
     public int getSum()
         {
         	int sum=0;
         	for (int i=0 ; i< convertedWorkArray.length ; i++)
         		sum+ = convertedWorkArray[i];
         		return sum;               		
         }

    Default Re: how to pass a variable from a method to another

    You need to give the getSum() method a parameter that accepts an int[]. Then you need to send it the int[] when you call the method:
    public int getSum(int[] arr)
         {
            int sum=0;
            for (int i=0 ; i< arr.length ; i++)
                sum+ = arr[i];
                return sum;                    
         }
